--accelerator=<accelerator type>

Specify the desired type of accelerator table. Valid options are 'Apple', 'Dwarf', 'Default' and 'None'.

--arch <arch>

Link DWARF debug information only for specified CPU architecture types. Architectures may be specified by name. When using this option, an error will be returned if any architectures can not be properly linked. This option can be specified multiple times, once for each desired architecture. All CPU architectures will be linked by default and any architectures that can't be properly linked will cause dsymutil to return an error.

--build-variant-suffix <suffix=buildvariant>

Specify the build variant suffix used to build the executable file. There can be multiple variants for the binary of a product, each built slightly differently. The most common build variants are 'debug' and 'profile'. Setting the DYLD_IMAGE_SUFFIX environment variable will cause dyld to load the specified variant at runtime.

--dump-debug-map

Dump the executable's debug-map (the list of the object files containing the debug information) in YAML format and exit. No DWARF link will take place.

Specify a directory that contain dSYM files to search for. This is used for mergeable libraries, so dsymutil knows where to look for dSYM files with debug information about symbols present in those libraries.

--fat64

Use a 64-bit header when emitting universal binaries.

--flat, -f

Produce a flat dSYM file. A .dwarf extension will be appended to the executable name unless the output file is specified using the -o option.

--gen-reproducer

Generate a reproducer consisting of the input object files. Alias for --reproducer=GenerateOnExit.

--help, -h

Print this help output.

--keep-function-for-static

Make a static variable keep the enclosing function even if it would have been omitted otherwise.

--minimize, -z

When used when creating a dSYM file, this option will suppress the emission of the .debug_inlines, .debug_pubnames, and .debug_pubtypes sections since dsymutil currently has better equivalents: .apple_names and .apple_types. When used in conjunction with --update option, this option will cause redundant accelerator tables to be removed.

--no-odr

Do not use ODR (One Definition Rule) for uniquing C++ types.

--no-output

Do the link in memory, but do not emit the result file.

--no-swiftmodule-timestamp

Don't check the timestamp for swiftmodule files.

--num-threads <threads>, -j <threads>

Specifies the maximum number (n) of simultaneous threads to use when linking multiple architectures.

--object-prefix-map <prefix=remapped>

Remap object file paths (but no source paths) before processing. Use this for Clang objects where the module cache location was remapped using -fdebug-prefix-map; to help dsymutil find the Clang module cache.

--oso-prepend-path <path>

Specifies a path to prepend to all debug symbol object file paths.

--out <filename>, -o <filename>

Specifies an alternate path to place the dSYM bundle. The default dSYM bundle path is created by appending .dSYM to the executable name.

--remarks-drop-without-debug

Drop remarks without valid debug locations. Without this flags, all remarks are kept.

--remarks-output-format <format>

Specify the format to be used when serializing the linked remarks.

--remarks-prepend-path <path>

Specify a directory to prepend the paths of the external remark files.

--reproducer <mode>

Specify the reproducer generation mode. Valid options are 'GenerateOnExit', 'GenerateOnCrash', 'Use', 'Off'.

--statistics

Print statistics about the contribution of each object file to the linked debug info. This prints a table after linking with the object file name, the size of the debug info in the object file (in bytes) and the size contributed (in bytes) to the linked dSYM. The table is sorted by the output size listing the object files with the largest contribution first.

--symbol-map <bcsymbolmap>

Update the existing dSYMs inplace using symbol map specified.

-s, --symtab

Dumps the symbol table found in executable or object file(s) and exits.

-S

Output textual assembly instead of a binary dSYM companion file.

--toolchain <toolchain>

Embed the toolchain in the dSYM bundle's property list.

-u, --update

Update an existing dSYM file to contain the latest accelerator tables and other DWARF optimizations. This option will rebuild the '.apple_names' and '.apple_types' hashed accelerator tables.

--use-reproducer <path>

Use the object files from the given reproducer path. Alias for --reproducer=Use.

--verbose

Display verbose information when linking.

--verify

Run the DWARF verifier on the linked DWARF debug info.

-v, --version

Display the version of the tool.

-y

Treat executable as a YAML debug-map rather than an executable.
